I prepared the stick (3 times, 3 downloads on different PCs, 3 different sticks), it ends up with the green „finished“ sign, I plug it into my NX4 , it starts as it is supposed to. While installing windows, it (everytime, different sticks) stops at 51%, saying it can not install required files.
Error code: 0x80070570
Make sure the stick is bigger than 8GB. Also, when you get the “green finished” dialog, does it give you and “Exit” button? I feel like when I did mine, we had to wait awhile to get the that (I could be wrong however). It also took us a couple of attempts on 2 different consoles. We did get it, but it does seem to have some hiccups in my opinion compared to previous updates.
